  Panchromatic donor–acceptor–acceptor sensitizers based on 4H-cyclopenta[2,1-b:3,4-b′]dithiophen-4-one as a strong acceptor for dye-sensitized solar cells

  摘要：

  Three new donor-acceptor-acceptor near-infrared organic dyes based on 4H-cyclopenta[2,1-b:3,4-b'] dithiophen-4-one as an additional acceptor were developed and used in dye-sensitized solar cells. By virtue of the simple donor-acceptor-acceptor configuration and systematic tuning of the electron-donating ability of the donor moiety, the absorption spectrum of HIQ3 on TiO2 extended to 900 nm. Remarkably, DSCs sensitized with HIQ3 showed broad incident monochromatic photon-to-current conversion efficiency spectra across the entire visible range and extending into the near-infrared region as far as 1100 nm.
